AIM: To study the process of troubleshooting of Operating System.
STEPS: 1.Identify the problem. 2.Establish a theory of Probable Cause 3.Test the theory to determine cause. 4.Establish a plan of action to resolve the problem and implement the solution 5.Verify full system functionality and if applicable implement preventive measures. 6.Document Findings, action and outcomes
PROCEDURE:
Step 1: Identify the problem.
OS problems can result from a combination of hardware, software, and network issues. Computer technicians must be able to analyze the problem and determine the cause of the error to repair the computer. This process is called troubleshooting. The first step in the troubleshooting process is to identify the problem.
Open-ended Questions
What problems are you having?
What OS is installed on the computer?
What updates have you performed lately?
What programs have you installed recently?
What were you doing when the problem was discovered?
Closed-ended Questions
Can you boot the operating system?
Can you boot up in safe mood?
Have you changed your password recently?
Have you seen any error on the computer?
Has any one used the computer recently?
Has any hardware been added recently?
Step 2: Establish a Theory of Probable Cause After you have talked to the customer, you can establish a theory of probable causes.
Step 3: Test the Theory to Determine Cause After you have developed some theories about what is wrong, test your theories to determine the cause of the problem. The figure shows a list of quick procedures that can help determine the exact cause of the problem or even correct the problem. If a quick procedure does correct the problem, you can jump to verifying the full system functionality. If a quick procedure does not correct the problem, you need to research the problem further to establish the exact cause.
Step 4: Establish a plan of Action to Resolve the Problem and Implement the Solution After you have determined the exact cause of the problem, establish a plan of action to resolve the problem and implement the solution.

Step 5: Verify Full System Functionality and Implement Preventive Measures After you have corrected the problem, verify full system functionality and, if applicable, implement preventive measures.
Shutdown the computer and restart it
Check event logs to make sure there are no new warnings or error.
Check task manager to ensure that the status of all programs is running
Re-run any third party diagnostic tools
Step 6: Document Findings, Actions, and Outcomes In the final step of the troubleshooting process, you must document your findings, actions, and outcomes.
Discuss the solution implemented with the customer
Have the customer verify that the problem has been solved
Provide the customer will all paperwork
Document any components used in the repair
Document the time spent to resolve the problem
RESULT:
Thus the process of troubleshooting of OS is studied.
